...while looking at the article I just spied "09JAN19" on the back of the display in the 5th image in the 3rd gallery (the teardown one).
Motorola have been working away at this for over a year.
And (probably...?) successfully kept it a secret.
And watched while Samsung's fold thing blew up.
With their own display probably already set in stone.
And it looks like they have a winner on their hands.
Hahh.
